I like the books Elif Shafak recommends. This website is also great! She is one of my favourite Turkish writers. The 40 Rules of Love is only one of her great books.
My other recommendations are;
1- The Sleeping Buddha by Hamida Ghafour
2- Ellis Island by Kate Kerrigan
3-The White Tiger by Aravind Adiga
4- Museum of Innocence by Orhan Pamuk
